/*
    Tests string alignment

    Normally strings are printed relative to the top left corner but this can be
    changed with the setTextDatum() function. The library has #defines for:

    TL_DATUM = Top left
    TC_DATUM = Top centre
    TR_DATUM = Top right
    ML_DATUM = Middle left
    MC_DATUM = Middle centre
    MR_DATUM = Middle right
    BL_DATUM = Bottom left
    BC_DATUM = Bottom centre
    BR_DATUM = Bottom right


    Needs fonts 2, 4, 6, 7 and 8

    Make sure all the display driver and pin comnenctions are correct by
    editting the User_Setup.h file in the TFT_eSPI library folder.
